HyGear has started the development of a recycling system for the float glass industry to recover the hydrogen and nitrogen from the tin bath. The opportunities lie in the reduction of the operational costs of utilities (hydrogen and nitrogen) and therefore fit well with the glass industry's aim of energy and cost savings.
HyGear‘s Gas Recovery technology is based on its proprietary Rapid Cycle VPSA technology. This technology is proven in the current hydrogen generation systems and is particularly suited for low-pressure inlet conditions that apply for in-line recovery of hydrogen-nitrogen. With the development of its VPSA-based GRS, HyGear aims to overcome short lifetime issues and unnecessary high costs of alternative recovery systems. These systems can be integrated with HyGear’s on-site hydrogen generators or applied as stand-alone systems.
Preliminary calculations show that with an off-gas collection of 40% - the rest is lost due to leakages within the tin bath - a hydrogen and nitrogen recovery of nearly 70% can be reached.
